Abstract
(EN)
A substantially spherical semiconductor ball implanted in orthopedic structures for sensing and/or stimulation. In one embodiment, a vertebral column (800) having a number of intervertebral discs (802) interspersed among respective vertebral bodies (804), material placed in intervertebral discs (802) allows for a semi-synthetic vertebral disc (806) to be constructed. The artificial intervertebral disk (806) contains one or more ball sensors (808) located within the body of the disk (806) in order to monitor the compression forces. Conventionally, the semi-synthetic disc (806) is monitored only retrospectively, and visualized on x-ray. In this particular embodiment, any of a number of semi-synthetic intervertebral discs (806) can be implanted with one or more ball sensors (808) such that stress and compression forces can be monitored to assure proper alignment of vertebrae (810) in the vertebral column (800), and to monitor the development of any nonphysiologic forces due to vertebral degeneration, disk malfunction, and so on.

Cette invention concerne une bille semi-conductrice sensiblement sphérique implantée dans des structures orthopédiques à des fins de détection et/ou de stimulation. Selon un mode de réalisation, l'invention fait intervenir un disque intervertébral semi-synthétique (806) destiné à une colonne vertébrale (800) comprenant un certain nombre de disques (802) disposés entre leurs vertèbres respectives (804). Le disque intervertébral artificiel (806) renferme un ou plusieurs capteurs sphériques (808) noyés dans le corps du disque (806), qui doivent permettre de surveiller les forces de compression. Classiquement, le disque semi-synthétique (806) n'est contrôlé que rétrospectivement et visualisé aux rayons X. Selon ce mode de réalisation particulier, un nombre quelconque de disques intervertébraux semi-synthétiques (806) peut être implanté avec un ou plusieurs capteurs sphériques (808). Il est ainsi possible de contrôler les efforts et les forces de compression pour garantir un alignement correct des vertèbres (810) dans la colonne vertébrale (800) et de surveiller l'apparition de forces non physiologiques par suite notamment de dégénérescence vertébrale ou de dysfonctionnement discal.
